Abstract (en)
[origin: EP0975001A2] A plasma display panel ("PDP") is provided with a protrusion (23) lower than barrier ribs (21) on an inner surface of a back plate substrate (20) and a phosphor layer (22) formed on a rib surface within a unitary emission unit including a surface of the protrusion, thereby realizing the PDP of high brightness, high luminous efficiency and long operating life. Also, the PDP has a structure, in which a portion of the inner surface of the substrate (10) is opened to a discharge space directly or through a protective layer, so as to improve power consumption remarkably. Further, the invention provides a production of the PDP with superior whiteness by way of controlling a balance of each color with shape of the respective protrusions. Moreover, an electrode can be formed easily and precisely on an upper part of the protrusion by providing a sloped surface for at least one end in a longitudinal direction of the protrusion. As a result, the invention provides the PDP that is of lower power consumption, high brightness, high luminous efficiency, and is capable of performing a speedy and stable electric-discharge and displaying white color of high color temperature.
